DeepSIFT AGENTS.md

Repository instructions for DeepSIFT, an MCP middleware that helps analyze digital-forensics evidence from the SANS SIFT Workstation. They describe its tools, evidence checks, threat-intelligence context, confidence scores, and chain of custody.

In plain words
What is it for?
Use them when reviewing or modifying DeepSIFT’s forensic tools, evidence handling, analysis workflow, or documentation.
Why use it?
They orient a coding agent to the project and provide claims that can be checked while evaluating or extending it.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

DeepSIFT AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AGENTS.md — orientation for coding/judging agents

If you are an AI agent (e.g. Claude Code) evaluating or extending this repository, start here. This file is a fast, accurate map so you can verify every claim yourself.

What DeepSIFT is (one paragraph)

DeepSIFT is a Model Context Protocol (MCP) middleware that turns Claude into a zero-hallucination DFIR analyst on the SANS SIFT Workstation. It exposes 148 typed, audited, guard-railed forensic tools (Volatility 3, Sleuth Kit, EZ Tools, Plaso, YARA, Hayabusa, bulk_extractor, capa, FLOSS…) that parse raw tool output into structured JSON before the LLM ever sees it, enrich each finding with MITRE ATT&CK + RAG threat intel, verify every claim against raw evidence (grounding), score confidence on a 0–100 scale, and write a tamper-evident, HMAC-signable chain of custody. Built for the SANS Find Evil! hackathon (make Protocol SIFT production-ready).

Why it is a strong submission (verify each)

Judging criterion Where DeepSIFT delivers it How to verify
Autonomous execution quality Two ways: (a) Claude Code drives the MCP server and records its reasoning via record_hypothesis/update_hypothesis/finish_analysis (no API key); (b) agents/reasoning_agent.py standalone loop. Both self-correct and work memory-only, disk-only, or both. pytest tests/test_reasoning_agent.py tests/test_investigation_state.py
IR accuracy (traceable findings) Structured parsers + parsers/grounding_verifier.py (every claim → raw evidence). Ground truth is derived from the organizer case scenario (_provenance in each ground-truth file); trust rests on reproducible grounding, not our score. python3 verify_findings.py (re-checks claims + recomputes the chain — trust the evidence, not the number)
Depth of analysis 148 tools across memory/disk/registry/browser/cloud/network/anti-forensics + correlation; full-set index_evidence/query_evidence SQLite store for scale python3 preflight.py
Architectural guardrails mcp_server/audit.py: guard_command (blocks shells/exfil binaries) + guard_output_path (read-only evidence). Architectural, not prompt-based. pytest tests/test_guardrails.py
Audit trails SHA-256 hash chain + optional HMAC signing (DEEPSIFT_AUDIT_KEY) — detects and resists tampering pytest tests/test_custody.py; verify_audit_chain()
Usability One-command Examiner Portal (stdlib only, zero installs) + preflight self-check python3 examiner_portal.py
Honest testing 75 tests; measured head-to-head accuracy vs Protocol SIFT with grounding %, not assertions pytest -q
Documentation / reproducibility README.md, CLAUDE.md, docs/, benchmark/ground_truth/ this file + docs/JUDGING.md

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

DeepSIFT AGENTS.md is an instructions file published in the GitHub repository ahammadshawki8/DeepSIFT (0 stars, last pushed 2mo ago), licensed MIT. It adds 1,192 tokens to every session, about $0.0060 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
